An amibitious project to pipe salt water from the Red Sea into the arid coastal city of Aqaba, Jordan, could turn the region into an oasis. A 50-acre demonstration facility, which will combine two technologies — seawater greenhouses and concentrated solar power — to grow crops, produce carbon neutral energy and desalinate seawater, has received approval from the government of Jordan and could be operational by 2012, with full-scale commercial use going online in 2015.
